So the shadow who appears with Shift-S can't get the flame.
Remember, the sign says: He who would steal the flame *must die*. The kid does not *really* die with Shift-S, so it's not good enough.
And then the "real" shadow comes and gets the flame.

But why does the kid's body remain there?
It seems that if the shadow dies (*), he can be resurrected at the kid's body, but then he will become another kid.
(*) This is possible at the flame, in a bottomless pit, or by Shift-K.
If the shadow dies, even the view changes to the kid's body.

Another bug I just found. (Near end o/t video.)
I was looking into something related to the flame and was wondering how the scripted event would react if the prince dies very close to the edge or room border, either looking left or right.
